Abought ledgeris a system inaccountingby which a business records and monitors itscreditors. The purchase ledger contains the individual accounts of suppliers from whom the business has made purchases oncredit. Information oninvoicesandcredit notesreceived, and payments made, are recorded in the supplier's account using thedebits and creditssystem, with thebalanceof each account at a given moment representing the amount currently owed to that supplier.
Historically, the purchase ledger was maintained in book form, hence the termledger, but in modern practice it is much more likely to be held on computer usingaccountancy softwareor aspreadsheet. The concept of Double-entry Bookkeeping is that debits balance the credits at all times. For convenience the main Trial Balance lists some accounts containing many entries as simply a single control figure. There is then a separate physical Ledger for the summarised area, which could conveniently be managed on its own, often at physically separate locations from the main ledger book. The Purchase Ledger is a common example of this.
The purchase ledger will ordinarily be an overall credit (liability) balance, unless credit notes or over-payments exceed the credit balance. However within itself, it is usual to show all invoices as positive figures, and payments as negative entries, as this minimises the number of negative entries to make/read.
Cambridgeshire (abbreviated Cambs.)[note 1] is a county in the East of England, bordering Lincolnshire to the north, Norfolk to the north-east, Suffolk to the east, Essex and Hertfordshire to the south, and Bedfordshire and Northamptonshire to the west. The city of Cambridge is the county town. Modern Cambridgeshire was formed in 1974 through the amalgamation of two older counties: Cambridgeshire and Isle of Ely, comprising the historic county of Cambridgeshire (including the Isle of Ely); and Huntingdon and Peterborough, comprising the historic county of Huntingdonshire and the Soke of Peterborough, which historically had been part of Northamptonshire. Cambridgeshire contains most of the region known as Silicon Fen.
The county is now divided between Cambridgeshire County Council and Peterborough City Council, which since 1998 has formed a separate unitary authority. In the county there are five district councils, Cambridge City Council, East Cambridgeshire District Council, Fenland District Council, Huntingdonshire District Council and South Cambridgeshire District Council.
